Report filter not working with DAX Calculation

Hi all,

I would like some help with this one please. I have the below DAX calculation and it is working fine:

TEST Custom Sales =
CALCULATE (
      [Sales],
      FILTER (
          SalesFact,
          RELATED('Date'[Financial Year]) = Max( 'Date'[Financial Year] )
          )
)

The issue is when I select a value from a report filter, for example Product = "Shoes", the calculation returns (Blank).. 

On the other hand when i specify a fixed value in the filter, the  product filter works fine:

TEST Custom Sales =
CALCULATE (
      [Sales],
      FILTER (
          SalesFact,
          RELATED('Date'[Financial Year]) = 2020
          )
)

Tables Date, Product, SalesFact are linked properly so there is no issues with the model. 

Can anyone help me resolve this problem?
